Abstract

The present study present the influence of SiCp incorporation on three-body abrasive wear behavior of glass/epoxy composites. The investigations was carried out using dry sand rubber wheel abrasive wear test apparatus. 2k factorial design of experiment was used to capture the experimental data. The parameters considered are abrading distance, load and speed. The wear volume loss found to increase with the increasing values of wear parameters. The applied load has exhibited significant effect on volume loss. Incorporation of SiCp contributed to enhance wear resistance of glass/epoxy composites. The linear regression was also presented in the study to correlate abrasion parameters with wear volume loss. SEM image analysis of abraded surface revealed the occurrence of ploughing, micro-cutting, matrix removal and fiber breakage.

Highlights

Polymer Matrix Composites (PMCs) are gaining popularity in many engineering applications like chute liners, gears, abrasive pumps, cams, bearings, bushes, bearing cages and other structural applications because of good mechanical and tribological characteristics

Summary

INTRODUCTION

Polymer Matrix Composites (PMCs) are gaining popularity in many engineering applications like chute liners, gears, abrasive pumps, cams, bearings, bushes, bearing cages and other structural applications because of good mechanical and tribological characteristics. Suresha et al [15] investigated the three-body abrasive wear behaviour of high-density polyethylene (HDPE)/ UHMPE composites reinforced with glass fiber and Zirconia (ZrO2). They have demonstrated that specific wear rate increases with increase in filler/fiber content of composites. Sahin [17] has employed 23 factorial design of experiments where 3 corresponding to abrading distance, applied load and abrasive size. The current research pays attention on the investigation of three-body abrasive wear behaviour of glass/epoxy composites with varied volume fraction of SiCp filler using factorial design of experiments.
